CIE Pass / Fail

For those users who want a convenient GO / NO GO colorimeter, this feature provides a method of defining an acceptability region that is displayed on a color CIE 1931 diagram following a measurement. If the measured color falls within the region, "Pass" is displayed, if not "Fail" is reported. Regions can be defined as square, rectangle, polygon (up to 10 sides) circles or ellipses. This feature is available on PR-655, PR-670, PR-680, PR-680L and PR-730/735 spectroradiometers. It is also available for the PR-521 ColorMate colorimeter. For the PR-521, no color CIE chart is displayed, and the region shapes can be defined as circles or rectangles only.

With the increasing popularity of LED lighting in markets such as the entertainment industry, one of the important criteria is the CRI of the light. The goal is to make sure the color rendering is as close as possible to existing technologies such as incandescent and HID lamps. At the NAB show earlier this year, many of the lighting manufacturers requested CRI directly on the instrument so we added it to the spectroradiometer lines (PR-655, PR-670, PR-680, PR-680L and PR-730/735). This feature provides all 14 indicies and the average CRI using indices 1 - 8. Results are reported on the instrument display.

3D / Temporal

Available for the new line of PMT based instruments - the PR-680, PR-680L, PR-805, PR-810 and PR-810L, the 3D temporal option provides the capability of measuring the device on / off characteristics and from these measurements calculate rise and fall times of the display, contrast ratio, min and max of all data and peak / valley photometric values. Designed to address the emerging 3D entertainment technologies, this feature can be used to quantify displays and interactive 3D glasses. This option can also be used to characterize the temporal (time dependent) performance of various display types (e.g. LCD). Results are reported graphically on the instrument display.

Photo Research has announced the introduction of its latest instruments, the PR-730/735 SpectraScans. These products are the latest in the SpectraScan series and feature a full color touch screen display, USB, RS232 or Bluetooth wireless interfaces, up to 8 measuring apertures and selectable bandwidths. The PR-730 is designed to cover the visible spectrum from 380 nm to 780 nm while the PR-735 measures from 380 nm to 1100 nm for near-IR applications.
"The SpectraScan series is used extensively in the automotive and aerospace industries because of the ability to measure small areas at low intensity levels. The PR-730/735 is better suited to these applications because of the 10X sensitivity improvement over the nearest relative, the PR-705/715." The new PR-730/735 products, like all Photo Research photometers and spectroradiometers, are unique in that they can be configured to address virtually all light measurement applications without changing instruments.

We are proud to announce the PR-680L SpectraDuo. Although similar to the PR-680 in almost every way, the PR-680L has a very important distinction - sensitivity. As you know the PR-680 is actually two instruments in one - a 256 detector spectroradiometer, and a PMT based filter photometer. In the case of the PR-680L, the PMT instrument side is over 14 times more sensitive than that of the PR-680. This means that this instrument is even more attractive for customers who want a total display measurement solution - it provides a greater capability for the hard to measure dark side of display contrast measurements. The total PMT dynamic range including all apertures is a staggering 360,571,400:1 with the automated internal ND-1 filter. The system dynamic range is 0.00007fL ti 5,000,000 fL.

We are pleased to introduce the PR-8XX series of instruments. The PR-805, PR-810 and PR-810L instruments are PMT based, have individually trimmed photopic filter, share the same packaging as the PR-655 / PR-670 / PR-680 including the full color touch screen display, USB, optional RS-232 & Bluetooth Interface, SD card measurement storage, and long lasting Li-ion battery. All three instruments feature an optional 3µs fast response analog output. They all have the following internal automated neutral density filters. ND-1, ND-2 & ND-3. The PR-805 is a single aperture system. The PR-810 and PR-810L each have four automated apertures standard. The PR-810L is a low level capability version of the PR-810 and can measure as low as 0.000003 cd/m² with a dynamic range of 512,000,000,000:1.

The new Photo Research PR-680 SpectraScan Duo combines the color accuracy of a spectroradiometer with the sensitivity and speed of a photometer. This is achieved by integrating a 256 sensor linear diode array spectroradiometer with a PMT-based photometer - all in a single battery-powered hand-held instrument. Features include a high-resolution touch-screen color display, four automated apertures, USB and Bluetooth connectivity, and SD measurement storage.

LR-127 LED Analyzer for PR-650, PR-705/715 and PR-880

The LR-127 is an optical accessory designed to measure discrete (3 mm or 5 mm packages) LEDs for parameters recommeded by CIE 127 Technical Report - Measurement of LEDs. Per this report the average luminous intensity (candelas) of the LED is determined by making two measurements - one measurement is made at a 2° cone (Condition A) and the second through a 6.5° cone (Condition B). The two readings are then averaged.

The LR-127 makes both measurements simply by sliding a lever to the A or B position. This means that the user does not have to change accessories to make both measurements.
